Anyone out there having problems with #alexa and #ikea #tradfri smart bulbs recently?
Our bulbs are connected to a Tradfri hub, and Alexa has the "Ikea Home smart 1" skill. The Tradfri hub is also integrated with our #homeassistant server.
Any lighting voice command issued via Alexa are taking a minute or more to take effect since about a week ago, but commands issued via the Ikea Home Smart 1 app (on iPhone), or Home Assistant, take effect immediately.
